Generally during the fall I'm wearing jeans, sweaters and a textured blazer, but in a sort of sloppy, unkempt (collegiate) way. Usually that means sneakers, but I'd like to diversify a little. I've tried to wear chukkas, wingtips, loafers, etc., but the niceness of these shoes ratchets up the slickness of the look more than I'd like. Are there any brown leather shoes to match my sloppy aesthetic? Would a pair of tan desert boots work?
